Puget Sound Clean Air Agency says these are the highest particulate levels so far this summer. The air quality in Western Washington reached “unhealthy for everyone” to “very unhealthy for everyone” Wednesday morning at most monitoring sites.

“Last summer we saw levels about this high and before that, in terms of summertime impacts, we haven’t really seen this in over a couple decades,” said Erik Saganic, air resources specialist for Puget Sound Clean Air Agency.

Saganic says people with breathing problems or compromised health should stay inside. Close the windows and doors. He says just doing that can cut fine particulate levels in half.
